Yeah, I tried deleting guisettings. I then reset all my settings back as before, rebooted and am back to 0.5 pixel ratio again. I'm starting to think it's an issue with the latest version of Confluence Modified which is a fault.

Following the instructions in Post: #1723 will address this problem. It takes guisettings out of the picture.

I believe you will find that, if you want to test, that starting from a fresh guisettings file, you won't have the 0.5 pixel ratio issue as long as you never use the gui calibrate feature. While this may be unsatisfactory because of excessive overscan, that can be corrected in config.txt, as indicated above.

allan thank you so much for this after a little tweaking of config.txt I have indeed got over this problem. You are also quite correct about deleting original guisettings.xml, I suggest your post #1723 should read

1. boot rpi
2. delete guisettings.xml to remove earlier anomolies
3. reboot
4. Edit guisettings to delete everything from <resolutions> to </resolutions>, inclusive
5. Insert <resolutions /> in the place of the (many) lines you just deleted.
6. save
4. login to the pi over ssh
5. type 'poweroff'
6. insert your SD card into your computer, to edit the the overscan settings in the config.txt file.
7. make all necessary adjustments other than calibration from gui

As a tool to do this from a windows I recomend MobaXterm Personal Edition v6.5 it allows a simple means of accessing the pi and has a built in editor
